Methods and devices for placing a target vessel in fluid communication with a source of blood and a target vessel. A conduit includes first portion adapted to be placed in fluid communication with a source of blood, such as a heart chamber, and a second portion adapted to be placed in fluid communication with a target vessel having a lumen, such as coronary artery. The first and second conduit portions are transverse to each other such that the conduit is generally T-shaped. The conduit lies on an exterior of the heart between the blood source and the target vessel and is configured to deliver blood in multiple directions into the lumen of the target vessel. For example, in an occluded coronary artery, blood flows both toward and away from the occlusion. The conduit may be flexible, rigid, collapsible or non-collapsible, and may be formed of synthetic vascular graft material, tissue, or a combination of the two. A conduit delivery device is disclosed for deploying the conduit in a target vessel and perfusing the vessel during such deployment.

Conduits for use in placing a target vessel in fluid communication with source of blood

Devices and methods for delivering conduits into the wall of a patient's heart to communicate a coronary vessel with a heart chamber. The devices are passed through the coronary vessel and the heart wall to place the conduit and establish a blood flow path between the vessel and the heart chamber. Additional devices and methods are provided for removing tissue from a coronary vessel or the heart wall to establish a flow path between the coronary vessel in communication with the heart chamber.

Delivering a conduit into a heart wall to place a coronary vessel in communication with a heart chamber and removing tissue from the vessel or heart wall to facilitate such communication

Anastomotic components may be attached to hollow bodies or vessels by magnetic or mechanical force to create an anastomosis, form a port in a vessel, or repair a diseased vessel lumen. Anastomoses are created by coupling a first connection to an end of a vessel and then attracting it to a second connector secured to the side wall of another vessel. The connection between the first and second connectors may be solidly magnetic, solely mechanical, or a combination thereof. Also disclosed are methods and devices for treating diseased vessel lumens, for example abdominal aortic aneurysm. A plurality of docking members is attached to the vessel at solicited positions, and then one or more grafts is secured to the docking members in any suitable manner.

Components, systems and methods for forming anastomoses using magnetism or other coupling means

Implantable prosthetic valve systems and methods for implanting them are provided. Magnets are employed within one or more components of the valve systems to facilitate anchoring of the prosthetic valve at a target implant site, delivery of the prosthetic valve to the target implant site or both.

Prosthetic cardiac valves and systems and methods for implanting thereof

A guide member positioned through a coronary vessel and the wall of the heart provides access to a heart chamber. A first end of the guide member is passed through the coronary vessel and the heart wall into the heart chamber, and then is passed back out of the heart chamber. The end of the guide member may then be used to deliver devices into the heart chamber to carry out various medical procedures. A conduit delivery system is coupled to the end of the guide member and is delivered into the heart chamber and then used to place a conduit in the heart wall to communicate the coronary vessel with the heart chamber.

Placing a guide member into a heart chamber through a coronary vessel and delivering devices for placing the coronary vessel in communication with the heart chamber

Methods and devices use magnetic force to form a magnetic port in a hollow body. Additional methods and devices form anastomoses between two or more hollow bodies. First and second anastomotic securing components create a fluid-tight connection between the lumens of the hollow bodies. End-to-side, side-to-side and end-to-end anastomoses can be created without using suture or any other type of mechanical fasteners, although mechanical attachment structure may be used in conjunction with the magnetic attachment. The securing components have magnetic, ferromagnetic or electromagnetic properties and may include one or more materials, for example, magnetic and nonmagnetic materials arranged in a laminated structure. The system of anastomotic securing components may be used in many different applications including the treatment of cardiovascular disease, peripheral vascular disease, forming AV shunts, etc. The system may be sized and configured for forming an anastomosis in or between a specific hollow body, for example, a coronary artery, the aorta, a radial artery, etc.
